Paint it like the one someone brought out to the field where I play the other day. Gold, all gold. Even the mag, let nothing escape the gold spray paint.

Seriously though, do like shifty said, and have it correspond to the vegetation of the area where you play the most. I would do something in a snake skin, as it both can work as a camo, and looks pretty epic.

However, if you have a wooden AK, I personally wouldn't mess with painting it, or anything silly like that, it looks amazing as is.
